. VAPORIZING' DEVICE FOR HEATING APPARATUS.

I Application filed September 11; 1920,] Serial No. 409,520,

To all whom it may concern I Be it known that LERNEsrDELiiAMoNT,

jeweler, citizen ofSwitzerland residing at. Marseille, in the'Republic ofFrance, have invented certain new and useful Improve-i ments in vaporizing Devices fonHeating' Apparatus, of which the following is a speci-;

fication. p

The present invention relates tohumidifiers; and it aims, briefly, to.provide'an im.'

proved humidifier for use in connection with any desired source of heat, butp'articularly adapted for hot water or steam radiators.

The principal object of the invention is to insure a uniform evaporation of the'liquid at highas well as atlow temperatures of the heater, this with a view to render it suitable for usein hospitals, sick rooms and the like; that is to say, in cases where, sincemedicaments may have to be added to the liquid to be vaporized, it is of the utmost importance that the evaporation take place uniformly regardless of the temperature of the heating source, as. an excessively-rapid evaporation of a liquid saturated with medicaments might possibly prove a real danger to the health of the occupants of the respective room.

According to the present invention, it is proposed to construct the humidifier in such a way as to prevent the heated air from circulating through the absorbent materal impregnated with the liquid to be vaporized but, on the contrary, to retain and keep it in intimate contact with said material so that the latter, even at low temperatures is enabled to absorb the greatest possible amount of heat. This material, which is non-pen iorated and in the form of a sheet or sheets is stretched like a roof across the space directly above the heating chamber so that a real heatin source is thereby produced by means of which the evaporation of the liquid with which-the absorbent material is saturated is effected as soon as the temperature of the heating chamber exceeds that of the surrounding air by 10 F. The absorbing power of the material used does prevent the latter from becoming sufficiently saturated if the temperature is rather high. As a consequence of the rapid evaporation caused accordance with the invention;

creased in such case, .due to the fact that the two superposed sheets cause considerable 4 regulatedgthe circulation oflair humidified 1 by the absorbent material beingproduced by thefiow of heated air risingfromjthe four. sides of the humidifier;v causing an agitation ofthe air. j

fIn the'accompanying drawings, Figure 1 is a perspective view of a radiator fittedwith a humidifier-constructed in' Fig.1.2' is an enlarged, cross-section or lfigl; .1 I Fig. 3*is' a planwiew, ofithe humidifier shown in Fig. 1-, with the cover omitted;

Fig. 4 is a "fragmental plan view of the 7 cover of said humidifier; Y

The improved device, as shown, comprises two trough-shaped receptacles g, h of trapez odial section, which "are kept apart by; means, of cross stays'jo and the plates, is, .75 of sheetfmetalpstrapsj being attached to; said endplatesfand ithewhole covered by a] platela of perforated sheet iron.) f The device, is a n ounted astride,the radiag tor, with-.thef'two troughs g and "h Testing on top thereof and the straps j engaging the end radiator sections to hold the device against endwise movement.

/Vhen the troughs are filled, the sheets 0 the troughs form the sides, while the end plates i form the ends. The cover is thenput on, and the vertically rising vapors are caught within the space enclosed by the said sheets 6 and. the inner-wallsof the troughs. Here rapid vaporization will take place; and even after the radiator has cooled down, for instance at night When the temperature has dropped to25- Q, vapori- Zing still takes place due to this enclosed space. It is of advantage. to use two super posed sheets of absorbent material, for experiments have demonstrated that the amount of liquid evaporated is greatly inadditional capillary action to be exerted and maintain between them a layer of liquid of about .1 millimeter in depth, at least when the sheets are arranged horizontally.

The two side parts of the cover it which are above the troughs g, k may be left unperforated for a width corresponding to that of the troughs, in order to prevent impurities from falling into the liquid. The middle part of the, perforated cover may be raise slightly above the sheets 6 and also at the sides in order to facilitate the heated air coming into contact with the sheets from the outside.

By filling the receptacles or troughs with an antiseptic liquid instead of with water, the room to be heated may be filled with antiseptic vapors, which is particularly useful in hospitals and sickrooms. Even by using ordinary clean water, the vapors Y- spaced relation and connected together of in at their opposite ends, said troughs adapted to straddle a source of heat so as to be disposed at opposite sides thereof, the inner side walls of the troughs and the connections between said troughs conjointly defining heating chamber which is closed at its ends but open at top and bottom; and imperforate liquidabsorbing material extending across the top of said chamber so as to form a roof for confining and retaining the heat in the chamber and having the opposite side portions thereof immersed in the liquid in said troughs.

2. A humidifier, comprising a pair of liquid-containing troughs connected to gether in spaced, relation and adapted to straddle a source of heat so as to be disposed at opposite sides thereof, the inner side walls of the troughs and the connections between said troughs conjointly defining a heating chamber which is open at top and bottom; imperforate liquid-absorbing ma terial extending across the top of said chamber to form a roof for confining and retain ing the heat in the chamber and having the opposite side portions thereof immersed in the liquid in said troughs; and a cover embodying imperforate side portions immediately overlying said troughs and a perforated central; portion immediately overlying said roof.

In testimony whereof I aifix my signature in presence of two witnesses.
